Alvarez will face Ortiz on Showtime PPV, while middleweight titlist Julio Cesar Chavez Jr., Mexico's other major boxing star, is also being penciled in to fight Sept. 15 on HBO PPV.

Who's going to blink? These things have a way of working themselves out, but who knows what will happen? It's always interesting to see how it unfolds.

It's not like one side will just walk away from the date, because the date is what is significant. Sept. 15 falls on Mexican Independence Day weekend, traditionally when a major Mexican fighter headlines a card.

Chavez has to first defend his belt against Andy Lee on Saturday night (HBO, 10 ET, along with a replay of last Saturday's controversial Manny Pacquiao-Timothy Bradley Jr. fight) at the Sun Bowl in El Paso, Texas. But if Chavez wins and comes out of the fight OK, Top Rank has talked about Sept. 15 being his next fight date.

During a teleconference with boxing reporters on Tuesday, Golden Boy Promotions chief executive Richard Schaefer was asked about the potential fallout of Alvarez and Chavez -- who also fight on competing Mexican networks -- both trying to fight on the same date.

"We are not concerned with what other promoters do," Schaefer said. "We are concerned with our own events."
